Although this is a significant recording in terms of music &
performance, it has some of the most flimsy packaging I have ever
seen.

This recording also features distinctly more string vibrato than
is usually advocated for Feldman's music, meaning that the overtone
sonorities do not blend to quite the degree possible. Although
this is a valid criticism, it's still an enjoyable recording of
this piece. It was the first, with the second following in the
same time frame (meaning that neither set of performers probably
even knew about the other effort), and there has been none since.
I do enjoy the performance here, but what with the attention to
Feldman's string music elsewhere, an updated interpretation could
be worthwhile.
